Is there a limit on how many connections be running in Mozilla v1.7.5 on dial-up?

I like to open multiple Web pages (up to 15 or more Web browser's tabs). 
I seem to notice I sometimes get "connection refused" errors on dial-up 
modem connections (24000-31200 conenctions; 3 KB/sec average). When I 
get these errors, Mozilla waits and doesn't continue processing. I have 
to hit OK to continue.

I do not get these errors with broadband connections on the same 
computer and browser. I like to load Web pages in the background while 
doing something else since dial-up is SLOOOOOOOOOOOOOOOOW.

Is it because dial-up can't handle it or something I need to tweak? I 
still get them even if I disable graphics on dial-up. I am using Windows 
XP Professional SP2 (all updates), Athlon 64 3200+, 1 GB of RAM, and an 
old USR Sportster 33.6k Faxmodem.

Thank you in advance. :)
